下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
下面参考附图描述本申请实施例的充电装置的测试***和方法,该充电装置的测试***和方法用于对充电装置的压降异常保护功能进行测试。
在本申请的实施例中,充电装置用于给待充电设备进行充电。待充电设备可以是指终端,该“终端”可包括,但不限于智能手机、电脑、个人数字助理(personal digital assistant,PDA)、可穿戴设备、蓝牙耳机、游戏设备、摄像设备等。充电装置可以是,适配器、移动电源(充电宝)或车载充电器等具有给终端充电的功能的设备。以适配器为例,充电装置可以VOOC适配器,VOOC适配器的充电电路可通过充电接口直接连接至待充电设备的电池。
可理解,充电装置设置有开关管,该开关管用于控制充电装置开启电能输出或关闭电能输出。在实际使用中,虚焊或驱动电压不足可能会导致开关管呈现电阻状态,充电装置在充电中会持续发热甚至烧毁。为了防止充电装置在充电中会持续发热甚至烧毁,充电装置具有压降异常保护功能,即检测开关管上的压降,当开关管的压降超过限定值时,认为出现压降异常,充电装置进入保护状态。
为此,本申请实施例的充电装置的测试***,在充电装置的测试中模拟前述压降异常,并查看充电装置是否会进入保护状态。例如,在开关管的控制极施加电压,并通过控制控制极的电压调整开关管上的阻抗,然后,在开关管的压降达到限定值,即出现压降异常时,查看充电装置是否会进入保护状态,从而验证压降异常保护功能的有效性。
下面结合图1-6详细描述本申请实施例的充电装置的测试***。
如图1-2所示,本申请实施例的充电装置的测试***100包括:充电装置10和电源模块20。
其中,充电装置10内具有开关管101和控制模块102。例如,开关管101可设置在充电装置10中充电电路103的输出端上,当开关管101导通时,充电电路103的输出端进行输出,当开关管101关断时,充电电路103的输出端停止输出。控制模块102可与开关管101的控制极相连,在充电装置10对待充电设备进行充电,即未进行压降异常保护功能的测试时,开关管101可在控制模块102的控制下导通或关断。控制模块102可为MCU(Micro-controller Unit,微控制单元)。
充电装置10还可具有充电接口104,充电接口104中具有电源线,充电装置10可通过充电接口104中的电源线向外部输出电能,例如为待充电设备的电池充电,或者向负载模块输出电能。具体地,如图2所示,充电接口104具有正电源线L+和负电源线L-,正电源线L+与充电装置10的充电电路103的正输出端+相连,负电源线L-与充电装置10的充电电路103的负输出端-相连,其中,开关管101与正电源线L+或负电源线L-串联连接。例如,在充电装置10通过充电接口104与待充电设备相连时,正电源线L+和负电源线L-可分别连接至电池的正极和负极,以为待充电设备的电池进行充电。
由此,通过控制开关管101的通断,可控制正电源线L+或负电源线L-与充电电路103形成通路或断路,从而控制充电装置10的电能输出。
电源模块20与开关管101的控制极连接,电源模块20用于向开关管101的控制极输出电压信号,以使开关管101的压降即开关管101的第一端与第二端之间的电压大于预设电压保护值。
控制模块102用于在开关管101的第一端与第二端之间的电压大于预设电压保护值时确认充电装置10是否进入保护状态,以对充电装置10的压降异常保护功能进行测试。
可理解,充电装置10内还可具有电压检测单元。控制模块102可通过电压检测单元检测开关管101的第一端与第二端之间的电压,并在充电装置10的压降异常保护功能正常且开关管101的第一端与第二端之间的电压大于预设电压 保护值时,控制充电装置10进入保护状态。而在充电装置10的压降异常保护功能故障或开关管101的第一端与第二端之间的电压小于等于预设电压保护值时,控制充电装置10处于正常工作状态。
在对充电装置10的压降异常保护功能进行测试时,通过电源模块20向开关管101的控制极输出电压信号,通过调整电压信号的电压值以调整开关管101的压降,当开关管101的压降大于预设电压保护值时,即模拟出压降异常的情况,此时判断充电装置是否会进入保护状态,从而确认充电装置是否具有压降异常保护功能,即如果充电装置进入保护状态,则确认充电装置具有压降异常保护功能或者压降异常保护功能有效,如果充电装置未进入保护状态,则确认充电装置不具有压降异常保护功能或者压降异常保护功能失效。
由此,能够有效测试充电装置的压降异常保护功能是否正常,确保充电装置的安全性及稳定性,避免因压降异常保护功能的问题导致充电装置出现售后问题,保证了充电装置的质量。
根据本申请的一些实施例,电源模块20输出的电压信号的电压值可手动调整,也可在控制器的控制下自动调整。例如,当手动调整时,用户可手动输入电压值或电压变化量,电源模块20可根据用户手动输入的电压值或电压变化量调整电压信号的电压值;又如,当自动调整时,控制器可根据开关管101的压降生成电压值或电压变化量,电源模块20可根据控制器生成的电压值或电压变化量调整电压信号的电压值。
具体地,如图3所示,充电装置的测试***100还包括:电压测量装置30,电压测量装置30连接开关管101的第一端和第二端,电压测量装置30用于测量开关管101的第一端和第二端之间的电压,以在开关管101的第一端与第二端之间的电压达到预设电压保护值时停止调整电源模块20输出的电压信号的电压值。其中,电压测量装置30为万用表。
当手动调整时,用户每次调整电源模块20的电压信号的电压值之后,电源模块20可根据用户的调整输出相应电压值的电压信号到开关管101的控制极, 然后,通过电压测量装置30测量开关管101的压降,用户可通过电压测量装置30查看测量到的压降,如果开关管101的压降达到预设电压保护值,则停止调整电源模块20的电压信号的电压值,如果开关管101的压降未达到预设电压保护值,则继续调整电源模块20的电压信号的电压值,直至开关管101的压降达到预设电压保护值。
同理,当通过控制器进行自动调整时,控制器每次调整电源模块20的电压信号的电压值之后,电源模块20可输出相应电压值的电压信号到开关管101的控制极,然后,控制器通过电压测量装置30获取开关管101的压降,如果开关管101的压降达到预设电压保护值,则停止调整电源模块20的电压信号的电压值,如果开关管101的压降未达到预设电压保护值,则继续调整电源模块20的电压信号的电压值,直至开关管101的压降达到预设电压保护值。
根据本申请的一个实施例,如图4所示,充电装置10可与负载模块40相连,例如充电装置10可通过充电接口104与负载模块40相连,其中,开关管101的第一端或第二端可通过充电接口104与负载模块40相连。作为一个示例,负载模块40可为恒流负载,例如,负载模块40为电子负载时,电子负载处于恒流模式,以使电子负载所处的回路中电流保持恒定。
可理解,当充电接口104可与负载模块40相连接时,充电装置10的充电电路103与负载模块40构成会回路,由于负载模块40可为恒流负载,因此,回路中的电流恒定,即流过开关管101的电流恒定。由此,通过负载模块40抽取固定电流,可便于对电源模块20的电压信号进行调整,只要逐渐降低或提高电压信号的电压值即可使开关管101的压降逐渐提高。
作为一个示例,开关管101可为MOS管或三极管。例如,如图5所示,MOS管的漏极D可为开关管101的第一端,MOS管的源极S可为开关管101的第二端,MOS管的栅极G可为开关管101的控制极。MOS管的漏极D可连接充电装置10的充电电路103,MOS管的源极S可连接充电接口104,MOS管的栅极G连接控制模块102,电流可从MOS管的漏极D流入,并从MOS管的源极S流出,电 流方向如图5中箭头方向所示。
进一步地,开关管101可为N型开关管,例如NMOS管或NPN三极管,此时,可逐渐降低电源模块20输出的电压信号的电压值。以NMOS管为例,电源模块20输出的电压信号的电压值越低,NMOS管的漏极D与源极S之间的阻抗越大,由于通过负载模块40抽取固定电流,流过NMOS管的电流恒定,因而,NMOS管的漏极D与源极S之间的压降也就越大。当电源模块20的电压信号的电压值低于某个电压值时,NMOS管的压降将会大于预设电压保护值。
或者,开关管101可为P型开关管,例如PMOS管或PNP三极管,此时,可逐渐提高电源模块输出的电压信号的电压值。以PMOS管为例,电源模块20输出的电压信号的电压值越高,PMOS管的漏极D与源极S之间的阻抗越大,由于通过负载模块40抽取固定电流,流过PMOS管的电流恒定,因而,PMOS管的漏极D与源极S之间的压降也就越大。当电源模块20的电压信号的电压值高于某个电压值时,PMOS管的压降将会大于预设电压保护值。
由此,在本申请实施例中,以N型开关管为例进行说明。通过调整开关管101的控制极上的电源模块20的输出电压(即电源模块20输出的电压信号的电压值),调整开关管101的阻抗,电源模块20的输出电压越低,N型开关管的阻抗就越大。使用万用表实时测量开关管101两端的压降,充电装置10用一个负载模块40抽取固定电流,调整电源模块20的输出电压,当电源模块20的输出电压低于某一电压值,即开关管101两端的压降大于预设电压保护值时,查看充电装置10是否会进入保护状态,从而确认充电装置10是否具有压降异常保护功能,从而,能够测试充电装置的压降异常保护功能是否正常,确保充电装置的安全性及稳定性,避免因压降异常保护功能的问题导致充电装置出现售后问题,保证了充电装置的质量。
作为一个示例,如图5所示,电源模块20可为直流电源DC,直流电源DC的正极与开关管101的控制极相连,直流电源DC的负极接地。可理解,在对充电装置10进行压降异常保护功能的测试时,可将充电装置10打开,直流电源 DC的正极直接连接到开关管101的控制极,直流电源DC的负极连接充电装置10的参考地。
根据本申请的一个实施例,如图6所示,充电装置的测试***100还包括:提醒模块50,提醒模块50与控制模块102相连,提醒模块50可在控制模块102的控制下对压降异常保护功能的测试结果或充电装置10的保护状态进行提醒,从而便于用户直观的了解测试结果。
可理解,当开关管101的压降达到预设电压保护值时,控制模块102可根据压降异常保护功能的测试结果或充电装置10的保护状态控制提醒模块50发出提醒信息,用户通过提醒模块50发出的提醒信息即可直观的了解测试结果,确认充电装置是否具有压降异常保护功能。
举例来说,当通过手动调整电源模块20的输出电压,使得开关管101的压降达到预设电压保护值时,用户即可查看提醒模块50是否发出充电装置进入保护状态的提醒,如果提醒模块50发出充电装置进入保护状态的提醒,则确认充电装置具有压降异常保护功能或者压降异常保护功能有效,如果提醒模块50未发出充电装置进入保护状态的提醒,则确认充电装置不具有压降异常保护功能或者压降异常保护功能失效。
又如,当通过控制器进行自动调整电源模块20的输出电压,使得开关管101的压降达到预设电压保护值时,控制器可向控制模块102发出状态提醒指令,控制模块102接收到状态提醒指令之后,可将用于指示充电装置10的保护状态的信息发送给提醒模块50,提醒模块50可根据接收到的信息发出提醒信息,如果提醒模块50发出充电装置进入保护状态的提醒,则确认充电装置具有压降异常保护功能或者压降异常保护功能有效,如果提醒模块50未发出充电装置进入保护状态的提醒,则确认充电装置不具有压降异常保护功能或者压降异常保护功能失效。
作为一个示例,提醒模块50可与充电装置10集成设置,例如,提醒模块50可为充电装置10上的指示灯。或者,提醒模块50可与充电装置10的控制 模块102进行通信,即控制模块102可将用于指示压降异常保护功能的测试结果或充电装置10的保护状态的信息发送给提醒模块50,提醒模块50可根据接收到的信息发出提醒信息,例如提醒模块50可为显示器,显示器可显示压降异常保护功能的测试结果或充电装置10是否进入保护状态。
综上,根据本申请实施例提出的充电装置的测试***,通过电源模块向开关管的控制极输出电压信号,以使开关管的第一端与第二端之间的电压大于预设电压保护值,控制模块在开关管的第一端与第二端之间的电压大于预设电压保护值时确认充电装置是否进入保护状态,以对充电装置的压降异常保护功能进行测试,从而能够有效测试充电装置的压降异常保护功能是否正常,确保充电装置的安全性及稳定性,避免因压降异常保护功能的问题导致充电装置出现售后问题,保证了充电装置的质量。
